Palomino Highlands

The Palomino Highlands is a hilly region of southeastern Los Angeles County which separates it from San Bernardino County. During the 1950s, the Palomino Freeway was built to help relieve congestion on the Great Ocean Highway and the Senora Freeway, bringing more traffic through the highlands. Also located in the highlands were the Boyle Heights oil fields and a Department of Homeland Security regional headquarters, and the highlands marked an abrupt end to metropolitan Los Angeles and the opening to the undeveloped areas of eastern Blaine County.
